Wherein, screw thread 13 is matched with 5 mouthfuls of end external screw threads of cryopreservation tube, for connecting cryopreservation tube 5 and collector 1；
Wherein, boss 11 is for placing quantity tube 2 and spring 4；Upper cover 14 can manual overturning realize collector switch, upper cover
Be machined with upper cover protrusion 141 on 14, after manual overturning upper cover 14, upper cover protrusion 141 with 2 upper end face contact of quantity tube and gradually under
Press quantity tube 2.
As shown in figure 4,2 one end of quantity tube is machined with liquid storage chamber 22, the other end is gradually reduced to form the conical surface 23, and conical surface bottom is flat
Pilot hole 21 is machined on face, pilot hole 21 extends to 22 end of liquid storage chamber, ultimately forms annular end face 25；Quantity tube 2 is close to lead
Multiple liquid-leaking nozzles 24 are evenly equipped with to the circumference in hole 21, and extend through the conical surface 23 always, so that 24 side of liquid-leaking nozzle and the external world
Connection and the other side is connected to liquid storage chamber 22.
As shown in figure 5, being successively machined on pricker 3, conehead 31, lateral liquid-leaking nozzle 32, annular convex platform 33, intercommunicating pore 34；
Lateral liquid-leaking nozzle 32 is located at the side of 33 principle upper cover 14 of annular convex platform, and is distributed along the even circumferential of pricker 3；Laterally
Liquid-leaking nozzle 32 and 34 connection of intercommunicating pore；Linked hole 34 is gas vent, is penetrated through always upwards along axis from 32 liquid-leaking nozzle lowermost ends whole
A pricker guarantees that 2 external and internal pressure of quantity tube is consistent to its end face, and saliva is flowed ultimately into cryopreservation tube 5.
Collector 1, quantity tube 2 are all made of transparent plastic processing, picker are facilitated to observe.
Erection sequence:
1, pricker 3 is machined with 34 one end of intercommunicating pore, is machined with 22 one end of liquid storage chamber from quantity tube 2 and is pushed into, finally, pricker
3 peripheries pass through quantity tube pilot hole 21, and 33 upper surface of annular convex platform is contacted with annular end face 25,33 outer circle of annular convex platform
There is cooperation with the design of 22 hole size of liquid storage chamber, can mutually be slided after the two contact and no leakage can be sealed；
2, spring 4 is put into along 31 one end of conehead of pricker 3, and guarantees that spring end face connects with 33 lower end surface of annular convex platform
Touching；
3, it finally installs component by above-mentioned and enters in collector 1 from 1 upper cover of collector, 14 side pressure, finally, 2 liquid storage of quantity tube
22 lower end surface of chamber is contacted with 1 boss of collector, 11 end face, and circular hole design has interference fit in 2 outer circle of quantity tube and collector 1,
And the two interference fit frictional force is greater than 4 elastic force of spring, finally ensures that quantity tube 2, pricker 3, spring 4 can all be fixed on collector
In 1, pricker 3 is in extreme higher position under 4 reaction force of spring at this time；3 conehead of pricker, 31 periphery passes through 1 through-hole of collector
12,31 outer circle of conehead and the design of through-hole 12 have cooperation, can mutually slide after the two contact and can seal no leakage.
